Service Identification Using Goal and Scenario in Service Oriented Architecture

초록

Recently, organizations face various business challenges because of rapidly changing user needs and expectations. SOA (Service-Oriented Architecture) is a promising technique for adequately handling them in organizations. In developing SOA based systems, service identification is one of the core activities, having a broad influence on the systems. To identify proper services, business goals and business change factors should be analyzed because the ultimate aim of SOA is to achieve business goals and business agility in turbulent business environment. To tackle this, we propose a service identification method based on goal-scenario modeling and a conceptual framework to elicit possible business changes. Traceability among business goals, business charge's and identified services are also constructed in this approach. We applied our approach into the HRS (Hotel Reservation System) domain to demonstrate its feasibility.
